    Samsung UE46B8090 Screen almost white

    Hallo everyone!
    I just registered to this Forum because I have a very uncommon problem.
    There is almost no (or very very little) colour on the screen.
    Pls have a look on the picture:



    Don´t care about the vertical stripes. They are caused from my camera.
    But if you look at the lower right corner you will see some grey stripes running from every letter towards the top of the screen.

    I haven´t seen such a fault before so I appriciate any help!!!
    Thanks so far

    Get better picture, adjust your camera settings to show this fault better.

    And *be careful* handling the TV. Very flexible with back removed.

    This is probably bad T-CON, this is hiding behind the internal stand bracket structure.

      Wow that was quick.
      Better picture could not be made before friday. But the pic above shows the problem very well. The "colours" are actually as u can see on the picture.

      Thought of the T-Con, too. BUT: its a 2009_240hz_frcq_v1.2 This T-con uses 2 parralel chips to feed the panel. So why is the whole screen "white" and not just a half of it?

        T-CON itself generates different voltages and drivers to operate the panel properly.

        Replace the T-CON.

        PS: Photo DOES not show the fault properly. ALL I see is whiteness even I looked close. We can wait till then for better picture.

            this is a LCD, not a plasma right?
            if so, the black upper left corner could indicate a cracked panel..

              HAHA gotcha!! It´s the sticker that comes with the TV from stock.
              The panel is def. not cracked. The picture itself is good/sharp but missing almost every colour......and has those bars running from every letter. So I think T-Con is not a bad guess. Haven´t seen this before. Thats why im asking here. Maybe s.o. has seen such type of fault......there´s nothing to find on the internet though.
              Oh and any other suggestions?
              Thank you anyway Scenic!!

                  Samsung LC32HG70QQUXEN - vertical and horizontal stripes across the screen
                  by kotel studios
                  Hi,

                  Just now my Samsung LC32HG70QQUXEN monitor gave up on me. On cold boots I get many vertical stripes going across the screen (see the attached picture). After it runs for 1-2 minutes those go away but there are horizontal stripes going across the whole screen no matter of the input and PCs I use. (couldn't take an picture of it since the image size goes to 20MB and the camera doesn't pick them up)

                  In a video about a 27" monitor with an similar issue the guy removes one resistor and supposedly the entire monitor goes back to life? For sure this fix is only temporary....

                  White screen repairs
                  by harp
                  To ask here... I have few devices with white screen problem, actualy nokia 2220 and some fuji? camera, and try to understand what is common problem to cause that issue.
                  Yes, both devices work everything else probably ok, I mean, I hear intro melody and keypress click sound, DTMF tone, power on off... all ok.
                  On desk is nokia 2220 slide, and I check all screen connectors and components arround it, measure voltage drop, but all looks ok. I suspect on slide flex cable, but it look ok and white screen is not interupt while flexing board, pushing conectors, and sliding up down. In attachment...

                  samsung galaxy ao2s very temperamental after screen replaced
                  by Chrissygizmo
                  Hi , I've recently replaced the screen in my Samsung galaxy ao2s, at first it wouldn't even turn on, it had the charging symbol on the screen when plugged in but the green circle wasn't going around to show it charging....
                  Ive eventually managed to get it on and working but it's very temperamental...

                  The battery icon always reads as 50% , when the phone goes into lock screen mode i sometimes can't get the screen back on unless I plug the charger in to get it to light up, also it keeps putting the camera app on.. u think it could be something to do with the side buttons. ...

                  Samsung UN55J6200AFXZA Splash Screen Comes up, goes out, screen flashes one time and then tv won't turn off.
                  No picture. No sound that I can tell. Backlights are on and have been checked. Flashlight test no image on screen. I replaced the Eprom chip hoping that was the problem but nothing changed.
                  Please help. Thanks in advance!

                  by Kiberge
                  HI guys!

                  I've got a Samsung LH82QENELGC/EN with a problem and need some advice and I hope this is the forum to use?
                  I'm from Norway so I'd like to apology in advance if my description of the fault is kind of simple or the names on the components are way off. 😊

                  the TV is powering up, working as normally and picture is all good, except a 1.5-inch-wide vertical line of snow/static across the screen.


                  This TV is a Signage Display/Public Display version and it's been used at my work for 4-5 years showing commercials 24/7. The fault occurred when...
